Using a buffer for requests

You may need a stream buffer (tnt_buf) if you don’t need the networking functionality of tnt_net, but you need to write requests or parse replies.

Creating a buffer

struct tnt_stream *tnt_buf(struct tnt_stream *s)

Create a stream buffer.

struct tnt_stream *tnt_buf_as(struct tnt_stream *s, char *buf, size_t buf_len)

Create an immutable stream buffer from the buffer buf. It can be used for parsing responses.

Writing requests

Use the basic functions for building requests:

• tnt_select() / tnt_insert() (see “Building a request with “tnt_stream””)
• struct tnt_request / tnt_request_compile() (see “Building a request with “tnt_request””)

Parsing replies

Use an iterator to iterate through replies in your stream buffer, or use the stream’s read_reply() method (stream->read_reply(struct tnt_stream *stream, struct tnt_reply *reply)).
